Hello,
192.68.82.0 255.255.255.0 route specifies all devices in the same subnet, so you can remove 192.168.82.247 and 192.168.82.103 routes and leave only 192.68.82.0 255.255.255.0.
Another important thing is to check if Masquerading option is turned on in the RUT955 device, if not please turn on this option.
You can do this by navigating to the NETWORK > FIREWALL > GENERAL SETTINGS
Regards,
